Accessing security codes within specific modules using VCDS (Vag-Com Diagnostic System) is crucial for performing certain adaptations, such as enabling the automatic window closing feature in rain. This article addresses the process of obtaining the “Vcds 09 Security Access” code required for activating rain-closing windows on a 2014 Volkswagen Jetta Highline equipped with a rain and light sensor (RLS).
Understanding VCDS 09 Security Access
The “09” in “VCDS 09 security access” refers to the Central Electrics module in the Volkswagen address scheme. This module controls various comfort features, including automatic window operation. To modify settings within this module, a 4-digit security access code is often required. This code acts as a safeguard, preventing unauthorized modifications.
Rain Closing Windows and Sensor Types
The ability to enable automatic window closing in rain often depends on the specific rain sensor installed in the vehicle. This particular Jetta has an RLS (Rain and Light Sensor), not the humidity sensor. It’s important to note this distinction, as the coding procedure and even the feasibility of the adaptation can vary between sensor types. As noted in a relevant forum discussion (linked below), vehicles equipped with only the RLS may encounter challenges when attempting this coding change.
Obtaining the Security Access Code
Unfortunately, the VCDS software itself does not provide the security access code. The code is specific to the vehicle and module. There are several potential avenues for obtaining this code:
- Official VW/Audi Documentation: Workshop manuals or technical service bulletins from Volkswagen or Audi might list the security access code for specific modules and model years.
- Online Forums and Communities: Online forums dedicated to VW/Audi vehicles often have threads discussing specific coding procedures, including security access codes. Researching forums like Ross-Tech’s (the makers of VCDS) can be helpful. The linked forum post highlights a potential issue related to the RLS and successful coding.
- Specialized Coding Services: Some companies and individuals specialize in VW/Audi coding and may have access to databases of security access codes.
Utilizing the VCDS Scan
The provided VCDS scan offers valuable information about the vehicle’s modules. Notably, it confirms the presence of the RLS in module 09 – Central Electrics:
Address 09: Cent. Elect. (J519) ...
Subsystem 1 - Part No: 1K0 955 559 AH ...
Component: RLS 180314 05 54 0403While the scan doesn’t directly provide the security access code, it confirms the hardware configuration is relevant to the desired adaptation.
Conclusion
Enabling rain-closing windows on a 2014 VW Jetta with RLS requires the correct VCDS 09 security access code. Obtaining this code might require further research through official documentation, online communities, or specialized coding services. The provided VCDS scan confirms the presence of the RLS, but the successful implementation of this feature may be challenging due to the specific sensor type, as indicated in online discussions. Refer to the linked Ross-Tech forum thread for more insights into potential complications and solutions.
